An Effect of Different Temperatures on the Mechanical Properties of Hot-Mix Asphalt with Rubber Addition

الملخص

Pavement surface properties are of paramount importance due to their direct relation to safety and ride comfort. The purpose of this study is to use the dry method to ascertain how crumb rubber affects flexible pavement. Rubber waste that has been mechanically ground or tire-ground into tiny pieces is known as crumb rubber. Both nations' road building and repair are impacted by this difference.  For instance, a significant quantity of petroleum asphalt is needed as a binder for pavement surfaces in Libya. Damage typically occurs due to high temperatures and rainfall. Because of tearing, cracking, and other types of degradation, these surfaces frequently exhibit a reduction in service life. The enhanced high toughness of each type may vary, and this can anticipate irreversible deformation as the temperature rises; additionally, this may have an impact on the pavement's durability and strength. With 2.5% Crumb Rubber (CR) improves indirect tensile strength (ITS) characteristics in the cold, low-temperature zone.Samples with a higher crumb rubber content failed more quickly at specific stress levels.
